Yes it is possible, but it depends on the genetic background of the plant. Some plants are naturally sequential bloomers and for such plants it will be not possible. But even for plants which can all bloom at once, it depends on how technical you want to get and how many resources and possibilities you have at hand to make it possible. For eg. in most hybrid Phals, Oncidiums and Cattleyas it is very possible, there is almost a fixed equation for that, but you need to monitor the temperatures, light, day length and lastly the fertilizers. For the average home grower it is difficult to achieve it all the time but sometimes it may happen naturally.
